Reexaminación paleoparasitológica de coprolitos de roedores procedentes de la Patagonia Argentina considerando información parasitológica actual

Abstract

Previous paleoparasitological studies were developed in Alero Mazquiarán an archaeological site located in the south of Chubut Province, Argentina. In those studies, coprolites from Cricetidae rodents (don’t identified) were examined and three species of parasites were found (Pterygodermatites spp., Trichosomoides crassicauda and Monoecocestus spp.). Among these parasites, the trichosomoidids are zoonotic nematodes and, in this sense, the paleoparasitological studies will allow to understand the distribution of parasites in time and space. Currently, new parasitological studies in sigmodontine rodents are being carried out in Santa Cruz Province, in an area near to that mentioned archaeological site. In this context, it is interesting to contrast the previously obtained results with the new information presented in the current study, to contributing to the interpretation of epidemiological models. This paper reexamines the identity of a nematode assigned to the family Trichosomoididae using morphological and molecular studies.
